Virtualization as a technology can offer tremendous benefits. It can also be deployed in several locations. For example, server virtualization, such as that offered by VMware, MS Hyper-V, and others, can leverage the power behind a few large physical servers by creating hundreds of virtual machines. Storage virtualization can bring the original promise of SANs to reality, by creating large storage pools and then virtually allocating capacity as needed. By combining these two technologies, however, users realize even greater value than what they would by using them individually. To virtualize the data center, these two technologies are required. This paper describes the benefits that can be realized by using the HP Storage Works SAN Virtualization Services Platform or SVSP solution in combination with the server virtualization technology.
